Final Project
Overview
Data Exploration
We will load the data as the first step in the data exploration.

## $ child_mortality : num 16.6 15.4 14.6 14.4 14.6 ...Checking for NA.
## [1] TRUE
There are NA in our data, We will impute NA using mice().
Rechecking for NA after imputation.
} 
We observe that NA were removed.
Here, We’ll further explore the data. First, We’ll look at min, 1st quartile, median, mean, 2nd quartile, max etc.

Boxplots
First look at the boxplots.
Histograms
We will see how the data is distributed (numeric fields) using histrogram.
Correlations
Now, we’ll look at the correlation matrix of the variables.
Building Models
Now, we are ready to build models. We will build model using df_imputed and compare the models. Then we will use the best model to predict child mortality.
We split df_imputed into training and test in 80/20 ratio and named as df_imputed_trn and df_imputed_tst.
